Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022508, here are decompositions:

5 + 1022503 = 1022508
7 + 1022501 = 1022508
17 + 1022491 = 1022508
41 + 1022467 = 1022508
59 + 1022449 = 1022508
79 + 1022429 = 1022508
127 + 1022381 = 1022508
131 + 1022377 = 1022508

Showing the first eight; more decompositions exist.
